Dear lukesblues,

“She is much prettier than this ex of the past and we are better matched and everything just feels good.”

This statement is enough to understand that you are comparing your current relationship with your ex.

“My problem is i cant help having thoughts about the ex and wanting to talk to her even though i know i now have a better relationship.”

This is understandable and you are not at fault. From what you have explained you still have the energetic cords (ties) of attachment with this person. These cords are invisible since they are at an energetic level. They are also called as psychic ties.
All you have to do is cut the energetic cords of attachment to get it out from your head so that you can be fully present.

Please go through the below links to know more on what it is and what to do-

Calling upon Archangel Michael with his golden sword is a very famous way of cutting negative cords-

There are many ways of doing this. Simply do a web search on “cutting energetic cords of attachment”

Also if you prefer something visual then there are lots of videos on YouTube too.

Take care,
